The newest trailer for Rogue One: A Star Wars Story debuted last night during the Olympics and in it we get a fleeting glimpse of the villain right at the end of the two-minute tease. He’s seen from behind standing in front of an illuminated display of the Death Star.

And then, we hear the Sith Lord’s breathing.

Rogue One — which is a stand-alone film set in the Star Wars universe — is set before the events of 1977’s Star Wars: A New Hope, when the Death Star is still under construction.

The film, which is being directed by Gareth Edwards (Godzilla), follows a young thief Jyn Ergo (Felicity Jones), who joins the Rebel Alliance in a mission to steal plans for Death Star. The new spot shows off secondary characters played by the likes of Diego Luna (playing Captain Cassian Andor, likely Ergo’s love interest), Forest Whitaker, Donnie Yen, Ben Mendelsohn (as the villain) and more. We also get fresh looks at Imperial Destroyers, AT-ATs, a face-to-face confrontation with a TIE fighter and K-2SO, who looks to be the scene-stealing new droid voiced by Alan Tudyk.

Rogue One: A Star Wars Story hits theatres on Dec. 16. It is the first in a series "Anthology" of spinoffs that will include a Han Solo prequel film due in 2018.
